Okay kiddo, let me explain the drinking game called 21.
So, first of all, a drinking game is a fun game that you play with your friends that involves drinking some sort of alcoholic drink.
In the game of 21, everyone playing sits around a table and takes turns counting aloud, starting at the number 1. The catch is that each person can only say one number at a time, and the numbers must be said in order.
So, the first person would say "1", the second person would say "2", and so on. When you get to the number 21, the person who says "21" gets to make a rule. This rule can be anything they want, like "everyone has to clap before they say their number" or "you can only say even numbers".
If someone messes up and says the wrong number or breaks the rule, they have to take a drink. And if someone can't think of a rule when they say "21", they also have to take a drink.
The game continues on like this, with each person taking turns counting and making rules. It's a fun way to hang out with friends and have a drink or two. But remember, even though it's a game, drinking too much alcohol is not safe or healthy for anyone, especially young children like you. So, if you ever decide to play a drinking game when you're older, make sure to drink responsibly and stay safe.
